Or. Admin. Code § 141-086-0200 - Definitions
(1) "Cowardin class
or subclass" means the wetland classification according to the U.S. Fish and
Wildlife Service's Classification of Wetlands and Deepwater Habitats of
the United States, Cowardin et al., 1979.
(2) "Director" means the Director of the
Oregon Department of State Lands or designee.
(3) "Department" means the Oregon Department
of State Lands.
(4) "Georeferenced"
means linking geographic data to known coordinates on the surface of the
earth.
(5) "GIS" or "Geographic
Information System" means a system of hardware, software and data storage that
allows for the analysis and display of information that has been geographically
referenced.
(6) "HGM class and
subclass" means the hydrogeomorphic classification of the wetland based upon
its landscape position and hydrology characteristics, according to the HGM
classification developed by the Department.
(7) "Indicator" means the soil, vegetation,
and hydrology characteristics or other field evidence that indicate that
wetlands are present.
(8)
"Inventory" means a systematic survey of an area to identify, classify and map
the approximate boundaries of wetlands, and includes the supporting
documentation required by these rules.
(9) "Mapping" means representing the
identified wetlands and their approximate boundaries on a map.
(10) "Offsite Determination" means a wetland
determination conducted without field verification using NWI maps, soils maps,
and aerial photographs.
(11) "Other
Waters" means waters of the state other than wetlands, such as streams and
non-vegetated ponds.
(12) "Probable
Wetland" or "PW" means an area noted during the course of LWI development that
appears to meet wetland criteria but is less than one half of an acre in size
or is small and of undetermined size, and is mapped as a point rather than a
polygon on the LWI maps.
(13)
"Sample Plot" means a specific area on the ground where soils, vegetation and
hydrology data are recorded on a field data form per OAR 141-90-0035(14) in
order to make a wetland determination.
(14) "Statewide Wetlands Inventory" or "SWI"
means an inventory that contains at minimum the location, type (e.g.
classification) and approximate extent of wetlands in the State of Oregon. This
inventory is continually revised as additional information is received or
obtained by the Department.
(15)
"Stream" means a watercourse created by natural processes, or one that would be
in a natural state if it were not for human-caused alterations. Stream includes
a channelized or relocated stream.
(16) "Visually confirm" or "visual
confirmation" means to walk over and/or visually check an area to make a
wetland determination and map wetlands and other waters.
(17) "Wetlands" means those areas that are
inundated or saturated by surface or ground water at a frequency or duration
sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil
conditions (ORS 196.800(16)).
(18) "Wetland Delineation Report" means a
written document that contains the methods, data, conclusions and maps used to
determine if wetlands and/or other waters of the state are present on a land
parcel and, if so, describes and maps their location and geographic extent. A
wetland determination report documenting wetland presence or absence is
included within this definition (OAR 141-090 et seq.).
(19) "Wetland Determination" means a decision
that a site may, does, is unlikely to, or does not contain wetlands. A
determination does not include the precise location or boundaries of any
wetlands determined to be present (OAR 141-090 et seq).
(20) "Wetland Mosaic" means a complex of
several wetlands that are interspersed between areas of non-wetland each less
than one half of an acre in size, or less than one tenth of an acre in size for
a WCP, making them difficult to map.
